Genera
Rabbits are small mammals in the family Leporidae of the order Lagomorpha (along with the hare and the pika). Oryctolagus cuniculus includes the European rabbit species and its descendants, the world's 305 breeds[1] of domestic rabbitSylvilagus includes 13 wild rabbit species, among them the seven types of cottontail. The European rabbit, which has been introduced on every continent except Antarctica, is familiar throughout the world as a wild prey animal and as a domesticated form of livestock and pet. With its widespread effect on ecologies and cultures, the rabbit (or bunny) is, in many areas of the world, a part of daily life—as food, clothing, a companion, and as a source of artistic inspiration.
Although once considered rodents, lagomorphs like rabbits have been placed in their own, separate family because of a number of traits their rodent cousins lack, like two extra incisors.





Rabbits: Habits, Diet & Other Facts

Rabbits are small mammals with fluffy, short tails, whiskers and distinctive long ears. There are more than 30 species around the world, and while they live in many different environments, they have many things in common.
Rabbits and hares are in the same taxonomic family, Leporidae, but they are in different genera. There are 11 genera within the family, but the term “true hares” refers only to species in the genus Lepus; all others are rabbits. Also, the American Rabbit Breeders Association (ARBA) recognizes 49 rabbit breeds.
Size
Some rabbits are about the size of a cat, and some can grow to be as big as a small child. Small rabbits, such as pygmy rabbits, can be as little as 8 inches (20 centimeters) in length and weigh less than a pound. Larger species grow to 20 inches (50 cm) and more than 10 lbs. (4.5 kilograms). 
According to Dr. Lianne McLeod, a veterinarian, in a column for The Spruce website, the largest rabbit breeds are the checkered giant, over 11 lbs. (5 kg); Flemish giant, 13 lbs. (5.9 kg) and over; giant papillon, 13 to 14 lbs. 5.9 to 6.3 kg); and giant chinchilla, 12 to 16 lbs. (5.4 to 7.2 kg). The world's longest rabbit, according to Guinness World Records, is a Flemish giant that clocked in at 4 feet 3 inches (129 cm) and 49 pounds (22 kg).
Small rabbit breeds include the Britannia Petite, under 2.5 lbs. (1.1 kg); Netherland dwarf, under 2.5 lbs.; dwarf hotot, under 3 lbs. (1.3 kg); and Himalayan, 2.5 to 4.5 lbs. (1.1 to 2 kg).



Offspring








Rabbits are known for their insatiable reproductive habits for good reason. They breed three to four times each year. This is because only 15 percent of baby rabbits make it to their first birthday, according to the Animal Diversity Web (ADW). So, to ensure that the population grows, rabbits have more babies. 
Each pregnancy produces three to eight babies, called kittens or kits. ("Bunny" is just an affectionate name for a rabbit, young or adult, according to Small Pet Select.) After four to five weeks, a kit can care for itself. In two or three months it is ready to start a family of its own. If there is a lack of natural predators, an area can quickly become overrun with rabbits.
Diet
Rabbits are herbivores. This means that they have a plant-based diet and do not eat meat. Their diets include grasses, clover and some cruciferous plants, such as broccoli and Brussels sprouts. They are opportunistic feeders and also eat fruits, seeds, roots, buds, and tree bark, according to ADW.
Habits
Rabbits are very social creatures and live in large groups called colonies. The busiest time of day for rabbits is at dusk and dawn. This is when they venture out to find food. The low light allows them to hide from predators. 
Predators — which include owls, hawks, eagles, falcons, wild dogs, feral cats and ground squirrels — are a constant threat. The rabbit’s long legs and ability to run for long periods at high speeds are likely evolutionary adaptations to help them elude things that want to eat them.

Classification/taxonomy

This is the taxonomy of rabbits, according to ADW, the International Union for Conservation of Nature (IUCN) and the Integrated Taxonomic Information System (ITIS):
Kingdom: Animalia Phylum: Chordata Subphylum: Vertebrata Class: Mammalia Order: Lagomorpha Family: Leporidae Genera
  • Brachylagus (pygmy rabbits)
  • Bunolagus (riverine rabbits)
  • Nesolagus (Sumatran rabbits, Annamite striped rabbits)
  • Oryctolagus (Old World rabbits, European rabbits, domestic rabbits)
  • Pentalagus (Amami rabbits)
  • Poelagus (Bunyoro rabbits)
  • Romerolagus (volcano rabbits)
  • Sylvilagus (cottontail rabbits)
Species: There are more than 50 species of rabbits. The domestic rabbit is Oryctolagus cuniculus.

Conservation status




Nesolagus netscheri, the Sumatran striped rabbit, is listed as vulnerable. It is a rare species, according to IUCN, and not well known locally. The species lives only on the island of Sumatra, Indonesia, at altitudes between 600 and 1,600 m (1,969 and 5,249 feet).
Pentalagus furnessi (Amami rabbit), which is found only on two Japanese islands, is endangered, according to the IUCN. Populations are declining because of invasive predators and habitat loss caused by forest clearing and resort construction. There are only about 5,000 individuals alive on Amami Island and 400 on Tokuno Island.

Other facts

Rabbits can be very crafty and quick. To get away from a predator, a cottontail rabbit will run in a zigzag pattern and reach speeds of up to 18 mph (29 km/h), according to National Geographic
Their ears can grow to 4 inches (10 cm). This stretched-out length allows them to better hear predators that may be approaching. It also allows them to stay cool in hot climates. Extra body heat is released through blood vessels in the ear.
Their eyes are made for safety, too, since each eye can rotate 360 degrees. This allows them to look behind them without turning their heads.
Rabbits don't get a lot of nourishment from their diet. They often eat their own excrement to access any remaining nourishment that their digestive system may have missed the first time.
